I have a pair of Pennants and a couple BOGS. The Pennants I dual feed. At each end I have a small box with a terminating resistor, relay and BN-73-202 binocular core transformer. I feed 12V through the RG6 which is all underground to select which direction. Without 12V the relay is not energized the terminating resistor is switched in. With 12V on the coax the relay switches in and the transformer is hooked up. Been doing it for years and it seems to work okay. I got some #75A/5975001401 cores. Going to double them up and use individual molded pairs of CAT5 I have as per K9YC for chokes. I plan on mounting the chokes in 4x4 water tight boxes and place on the ground or low on nearby trees where the RG6 comes up out of the ground. Should I attach the shield of the RG6 at the box to a ground rod or let it float? If I should add a ground rod should I put it on the antenna side or the shack side of the box? For the BOGs I just use a binocular core matching transformer at the feedpoint and a series cap since there is 12V on the coax. I have a ground rod at the feedpoint and at the termination. I plan on just using a very short piece of RG6 between the matching transformer and the choke since there is already a ground rod close by. Comments and recommendations welcome. 73, N2TK, Tony
